Sizing Your AC for the Living Room
Living rooms have unique challenges: high foot traffic, large glass windows, kitchen heat spillover, and irregular shapes. Always size UP by 10–20% compared to a bedroom of the same area. Use our Room Size Calculator for a precise recommendation.
| Living Room Size | Recommended Capacity | Notes |
|---|---|---|
| Up to 150 sq ft | 1.5 Ton | Small apartment hall |
| 150–200 sq ft | 1.5–2 Ton | Standard living room |
| 200–280 sq ft | 2 Ton | Large living room |
| 280+ sq ft | 2 Ton × 2 or Cassette AC | Open plan or large hall |

Living Room AC Installation Tips
Central Wall Position
Mount on the wall adjacent to the longest side of the room. Centre placement ensures even air distribution to all corners.
Avoid Direct Sunlight
Don't mount the indoor unit on a wall that receives direct sunlight — it makes the thermostat sense higher temperatures and run longer.
Enable 4-Way Swing
Use horizontal + vertical swing for maximum air coverage in large open-plan living areas.
Seal Gaps
Check that doors, windows, and AC penetrations are sealed. Living rooms often have more air leaks than bedrooms.
Frequently Asked Questions
Should I get 1.5 ton or 2 ton for my living room?
For rooms up to 170 sq ft, 1.5 ton is sufficient. For 180+ sq ft, or rooms open to a kitchen/dining area, choose 2 ton. When in doubt, size up — an oversized AC by 10–15% is far better than an undersized one.
Is one AC enough for a large open-plan living-dining area?
A single 2-ton split AC can handle up to ~250 sq ft effectively. For larger open-plan spaces (300+ sq ft), consider two 1.5-ton ACs on opposite walls, or a cassette AC in the ceiling.
How long does it take to cool a living room?
A correctly sized AC cools a living room to 24°C in 15–20 minutes from 40°C outside temperatures. An undersized AC may never achieve set temperature, running continuously and wasting electricity.
What is the ideal AC temperature for a living room?
24–26°C is optimal for comfort and efficiency. Each degree below 24°C increases energy consumption by approximately 6%. Set 25°C with fan on auto for the best balance.
